We reported it. The head was rejected. The fabricator cried foul. We re-scanned with conventional UT. It showed nothing. We cut a coupon. The unbond was confirmed: a 0.05 mm gap filled with oxidation.
The lesson: if you only use conventional UT, you accept unbonds that will fail in service. That’s not inspection. That’s gambling.
Data Recording, Reporting, and Full-Coverage Automation
You can’t defend a repair without data. Digital traceability is non-negotiable.
Encoded scanning : Use an encoder that tracks probe position within ± 0.5 mm. Motorized scanners are best for large plates. Manual encoded scanning works for smaller plates. The encoder feeds X-Y coordinates to the PAUT software. Every data point is indexed.
C-scan mapping : The software creates a color-coded map. ʻOmaomao = amplitude ma lalo 20% o ka hoʻolālikelike reflector. Melemele = 20–40%. ʻulaʻula = luna 40% (hoʻokuʻu). E hoʻonoho i ka paepae e pili ana i kāu kūlana ʻae.
